Inaccurate relay settings and missing coordination studies cause cascading nuisance trips, catastrophic damage to critical transformers and generators, and severe grid non-compliance penalties.
We build comprehensive power system models for industrial facilities and utility substations, determining symmetrical and asymmetrical fault currents, plotting coordinated time-current curves (TCC), and supplying validated configuration files.
From analytical system calculations to numerical IED configuration files
Comprehensive network modeling in ETAP software determining balanced and unbalanced fault currents in strict accordance with ANSI/IEEE and IEC 60909 standards.
Rigorous calculation of Time-Current Characteristic (TCC) curves ensuring time and current grading across all protective stages from generation to low-voltage feeders.
Engineering and validation of configuration files and programmable logic schemes for leading global relay manufacturers (SEL, Siemens, Schneider, ABB/Hitachi).
Determination of incident energy levels and arc flash boundary distances across medium- and low-voltage switchgear per IEEE 1584 and NFPA 70E.
Advanced analytical suites and multi-vendor numerical IED mastery
Industry-standard simulation and drafting software utilized for power system design and analysis
Power Simulation & ProtectionComprehensive electrical network modeling for short-circuit analysis (ANSI/IEC), steady-state load flow, and Time-Current Coordination (TCC) curve development.
Electrical CAD & Schematic DesignEngineering development of executive single-line diagrams, high-voltage substation physical arrangements, three-line schematics, and relay panel wiring.
Electromagnetic Transients (EMTP)Detailed simulation of high-voltage electromagnetic transients, breaker switching overvoltages, lightning strike surges, and insulation coordination.
Industrial Analysis & SelectivityAnalytical evaluation of complex industrial power distribution networks, circuit breaker interrupting duty checks, and arc flash hazard evaluations.
Technical details regarding scope, lead time, and deliverables
Lead time depends on network size and relay count. Standard medium-voltage facilities take between 15 to 30 business days, including interim reports for utility or grid operator alignment.
Yes. All our studies and reports are signed by licensed, credentialed professional electrical engineers with full legal and regulatory backing.
Absolutely. In addition to theoretical studies, our field commissioning engineers can flash the parameter files onto the IEDs and execute secondary injection tests with OMICRON test sets to verify tripping behavior.
